The project has a 520-calendar-day completion timeline, with a mandatory pre-bid meeting scheduled for December 4, 2026, at 11 AM at the project site. Sealed bids are due by 2 PM local time on January 21, 2026, and bidders must submit any questions by December 15, 2025, with compiled responses to be posted by January 8, 2026.

The procurement emphasizes non-discrimination and provides full bidding opportunity to Minority Business Enterprises, Disadvantaged Business Enterprises, Women-Owned Business Enterprises, and Veteran-Owned Business Enterprises. Bidders must provide a performance bond and payment bond equal to 100% of the contract price. The project includes a base bid with two primary items: Mobilization and Demobilization (with a fixed maximum lump sum of $25,000) and Improvements to Griffith Lake Dam, along with unit price items for additional work such as steel H-pile installation, riprap, excavation, and aggregate placement. A contingency allowance of $75,000 is included to address potential repairs or additional work identified during construction. Prevailing wage rates have been established, with hourly rates varying by construction trade classification and ranging from $15.00 to $116.61 per hour across Delaware counties. The project is funded by the State of Delaware and will be executed under a single prime contract, with the Owner reserving the right to reject any or all bids and waive informalities.
